The 2014 Annual Review is part of EPA’s development of the 2014 Effluent Guidelines Program. Once the public review and comment period has expired, ‘EPA will prepare and publish the Final 2014 Plan’.

EPA solicited information from the public on wastewater discharges of nanomaterials, particularly nanosilver, before, in its Final 2010 Effluent Limitations Guidelines Plan. On that occasion there was much enthusiasm for investigating the ‘environmental and human health risks’, but ‘commenters provided little or no data information regarding potential risks’.
